Overview
The STG3699AUTR is a high-speed CMOS low voltage quad analog SPDT switch or 2:1 multiplexer/demultiplexer fabricated in silicon gate C2MOS technology. It operates from a single supply of 1.65V to 4.3V and features very low ON-Resistance (RON <0.5Ω at VCC=3.0V). The device includes fast switching speed, break-before-make delay time, and ultra-low power consumption. All inputs and outputs are equipped with protection circuits against static discharge, providing ESD immunity and transient excess voltage tolerance. It is available in the commercial temperature range (-55°C to 125°C) in a QFN16 package.
Feature Summary
- Quad SPDT switch configuration with 2:1 multiplexer/demultiplexer capability
- Ultra-low ON-resistance for minimal signal loss
- Fast switching speed with break-before-make delay
- Integrated ESD protection on all inputs and outputs
Applications
- Portable applications requiring low voltage operation
- Audio signal routing
- Video switching
- Mobile and communication systems
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package type matches design requirements, as variants exist in different QFN dimensions. Check RoHS compliance status if environmental regulations apply to your specific application context.
Selection Notes
Select this component when low voltage operation between 1.65V and 4.3V is required. Ensure compatibility with control logic levels, noting the 4.3V tolerant and 1.8V compatible threshold on digital control inputs. Consider the operating temperature range and package size constraints for your PCB layout.
Part Context
The STG3699A series includes variants such as STG3699AQTR and STG3699AUTR, differing primarily in packaging. The AUTR suffix indicates tape and reel packaging in the QFN16 (2.5x2.5mm) format. Other family members like STG3699B offer similar functionality but may differ in package dimensions or specific electrical characteristics.
Replacement Considerations
STG3699AQTR serves as a direct replacement with identical electrical specifications but utilizes a QFN16 (3x3mm) package. Verify footprint compatibility before substitution due to the difference in physical dimensions between the 2.5x2.5mm and 3x3mm packages.
